3. The vehicle information update method according to claim 2 , wherein the first wireless access means is selected based on a data size of the latest software or a data size of the latest map information.

4. A vehicle information update method in a mobile device having near-field communication (NFC) functionality comprising: receiving location information or travel route setting information of a vehicle from an in-vehicle device through NFC tagging; transmitting a predetermined control message including the location information or the travel route setting information to an update server over a wireless network; receiving latest software or latest map information corresponding to the location information or the travel route setting information from the update server over the wireless network; and transmitting the received latest map information to the in-vehicle device using an available wireless access means in the vehicle, wherein the latest software is received when the NFC tagging is sensed while software version information is displayed on a display screen of the in-vehicle device, and the latest map information is received when the NFC tagging is sensed while map version information is displayed on the display screen of the in-vehicle device.

5. The vehicle information update method according to claim 4 , wherein the location information or the travel route setting information is received by the NFC tagging on a navigation screen of the in-vehicle device.

6. The vehicle information update method according to claim 5 , wherein, when the navigation screen is a screen to display a travel route based on an input of a destination, the travel route setting information is received.

7. The vehicle information update method according to claim 5 , wherein, when the navigation screen is a screen to display only a current location of the vehicle, the location information is received.

8. The vehicle information update method according to claim 4 , wherein, when the travel route setting information is received, the latest map information is changed map information based on the travel route.

9. The vehicle information update method according to claim 4 , wherein, when the location information is received, the latest map information is changed map information within a predetermined radius from a current location of the vehicle.

10. A vehicle information update system using near-field communication (NFC) comprising: an update server to transmit latest vehicle software and latest map information over a wireless network according to an external request; an in-vehicle device having NFC functionality and being configured to sense NFC tagging through a display screen, the in-vehicle device transmitting first information including at least one item selected from a group consisting of: location information, travel route setting information, software version information, and map version information according to type of the display screen, through NFC connection; and a mobile device having a processor installed therein to transmit a predetermined control message including the first information to the update server over the wireless network upon receiving the first information from the in-vehicle device, to receive the latest software or the latest map information based on the first information over the wireless network, and to transmit the received latest software or the received latest map information to the in-vehicle device using a wireless access means in the vehicle, wherein the latest software is received when the NFC tagging is sensed while the software version information is displayed on the display screen, and the latest map information is received when the NFC tagging is sensed while the map version information is displayed on the display screen.

11. The vehicle information update system according to claim 10 , wherein the mobile device selects the wireless access means from a group consisting of: a Wi-Fi Direct connection, an NFC connection, and a Bluetooth connection, based on a size of the latest software or a size of the latest map information.

12. The vehicle information update system according to claim 10 , wherein the wireless network includes: i) a wireless Internet network supporting at least one wireless access means selected from a group consisting of: Wi-Fi, Wibro, and Wimax and ii) a mobile communication network supporting at least one wireless access means selected from a group consisting of: WCDMA, HSPA, LTE, and LTE-A.

13. The vehicle information update system according to claim 12 , wherein the mobile device selects the wireless access means based on at least one factor selected from a group consisting of: a wireless connection state, data communication expenses, and a data transmission speed per wireless access means.

14. A vehicle information update apparatus interlocked with a mobile device through a near-field communication (NFC) connection comprising: a short-range communication module having a processor installed therein that is configured to: sense NFC tagging on a display screen of the apparatus; transmit first information including at least one item selected from a group consisting of: location information, travel route setting information, software version information, and map version information, according to a type of the display screen, to the mobile device through the NFC connection; and receive latest software or latest map information corresponding to the first information from the mobile device through a first wireless access means in a vehicle, wherein the latest software is received when the NFC tagging is sensed while the software version information is displayed on the display screen, and the latest map information is received when the NFC tagging is sensed while the map version information is displayed on the display screen.
